It actually happened to an old member here (no longer posts) named dieselshop. I saw the cam myself.

He was just driving to work in the morning and heard a pop. Engine running on two cylinders. He turned it around and drove home.

Lucky for him we had just finished rebuilding a junkyard 22RE to throw inside after he saw my rod bearing let go.
